IS it possible Channel was the test case? with other ITV station helping out just to see what the results where?
I doubt it, why experiment with the poorest station?
Of course place like Channel and Grampain are remote and would benefit the most for the introduction, I doubt there would be any real benafit for Thames?
I think not having to develop film would have been a substantial benefit for all TV companies.
Yes, that was the prime motive. There was still the requirement to bike the tapes back to a studio, or inject point, it wasn't until the mid 80s, that SHF links started to get used to send material back to base, and of course opening the Pandora's Box of pointless live reports with nothing to say from doorsteps etc Amen
TVS used a helicopter as a quickly deployable SHF mid point, it cost a fortune to run, but worked brilliantly.
Then of course from the early 90s satellite uplinks became viable, and today we're moving onto 3/4G.
